CS3.241

C-Line

The output voltage is floating and has no ohmic connection to the ground. Type and factory tests are conducted by

the manufacturer. Field tests may be conducted in the field using the appropriate test equipment which applies the

voltage with a slow ramp (2s up and 2s down). Connect all input-terminals together as well as all output poles before

conducting the test. When testing, set the cut-off current settings to the value in the table below.

To fulfil the PELV requirements according to EN60204-1 § 6.4.1,

we recommend that either the + pole, the – pole or any other

part of the output circuit shall be connected to the protective

earth system. This helps to avoid situations in which a load starts

unexpectedly or can not be switched off when unnoticed earth

faults occur.
